1. (Mong)- Slang for spastic, but used against a person who says or does something completely idiotic by accident or without realisation. This makes every witness simultaneously raise their hands to their shoulders and shake 'em while sticking their tongue in their lower lip and making 'urrgh' noises.

2. (Monged)- A vegetive state of mind/being usually effective after consuming large quantities of alcohol, weed, lsd, ecstacy etc or combinations of.

1. Steve you mong, you've just poured the kettle onto ya cornflakes.

2. Steve's well monged after we spiked his drink with acid, muhahahaha.

Mong is short for 'mongoloid', which was originally an anachronistic term for a Down's Syndrome sufferer. The modern Mong however is a total fuckwit, who deserves nothing less than complete humiliation for their idiocy. That includes all those dope smokers too, who relate being 'monged' to being chilled and mellow. Its because when you're stoned you act like a fucking retard, you fucking spazzes!

A shortened version of the Shakespearian insult 'fish monger' from Hamlet directed at Polonius. There is debate to what the original meaning was but it usually donates to the nature of the fishmongers of the time who were money grabbing, corrupt, stereotypically simple and of low moral fiber. So mong generally refers to a despicable and or stupid person.

(Disclaimer: this is not a stab at anybody associated with the fishing industry. it is just an interpretation of another mans writing and opinions)
